A critical firmware issue affecting a batch of Qolsys IQ Panel 2+ systems has recently been discovered. This issue
may cause affected units to automatically reboot in certain cases.

Corrective Action:

A firmware upgrade has been developed to correct this issue. This firmware has been made available
immediately for installation via patch tag and can be applied to any affected panel with software version 2.4.2 or
higher. This update will also be made available for remote upgrades via the Alarm.com partner portal in the near
future. Lastly, future versions of IQ Panel 2+ software (i.e. 2.5.5, 2.6.0, etc) will include the necessary firmware fix.
This upgrade is mandatory for all new installations as well as for all existing Qolsys IQ Panel 2+ installations if the
hardware used is from the affected batch. You should apply it to existing systems either locally via patch tag or
remotely once the new firmware is available on the Alarm.com portal.

Affected Qolsys SKU’s:

All IQ Panel 2+ SKU’s manufactured from 2020, Week 35 or Week 37 (depending on the factory code) through
2021, Week 05 are affected. This corresponds to Date Codes G035 - G105 and J037 - J105 (digits 6-9 of the
Panel Serial Number).
The Panel Serial Number (SN) may be found on the Panel box, back of Panel and in the ABOUT menu of the
Panel software. Panels with software 2.5.0 and higher also report their SN on the Alarm.com partner portal:
